Thought i would share a few photos of a pied painted i bred from a pr of normal red painteds. It is more grizzle coloured. The bill has changed from black and red to a bright red. Always thought there was something funny about it compared to its sisters. Wasn't til i caught it up i noticed the pied markings. Just paired it up with an unrelated red male. Does anyone know the mode of inheritance for pied Painteds?

I cringe whenever I hear of "mating back to a parent" to produce extra coloured birds. The parents as mated produced this one so if it is a heritable mutation they should do it again anyway. I would do just as you have & mate to a normal (preferably the best quality one you could get) to breed splits. If you breed another pied from the same parents I would mate it to a normal of different blood to the male you paired this one to in order to get two separate lines (relatively) of splits to pair back together next generation. If the adult pair haven't produced more pieds before next season, I would separate this one from the male you are pairing her to (after they produce some splits) & mate her with a different blood male. Try to use only the best available normals so that quality improvements can be made every generation throughout establishment - then by the time you establish them they will be nice birds which will appeal to others. When mutation establishment becomes a race to get as many coloured birds on the perch in the quickest possible time, the birds look burnt out by the time you get to establishment point. If you take a more patient approach with emphasis on the quality of the bird using regular good quality outcrosses right from the start & regularly throughout the process whilst selectively improving the pied trait, you will end up with something far more worthwhile.
